CA 2704919

A system and method for detecting and tracking multiple objects on a touchpad or touchscreen, wherein the method provides a new data collection algorithm, wherein the method reduces a calculation burden on a processor performing detection and tracking algorithms, wherein multiple objects are treated as elements of a single object and not as separate objects, wherein the location of the objects are treated as end-points of a single object when two objects are detected, and treated as a perimeter or boundary when more than two objects are detected.

L'invention porte sur un système et sur un procédé pour détecter et suivre de multiples objets sur un pavé tactile ou un écran tactile, le procédé fournissant un nouvel algorithme de collecte de données et réduisant une charge de calcul sur un processeur effectuant des algorithmes de détection et de suivi, de multiples objets étant traités en tant qu'éléments d'un objet unique et non en tant qu'objets distincts, l'emplacement des objets étant traité en tant que points d'extrémité d'un objet unique lorsque deux objets sont détectés, et en tant que périmètre ou frontière lorsque plus de deux objets sont détectés.
